As PHP grows, more versions show up with better stability & performance, obviously we test our code against production environment, but what if we could test it against new versions with little effort and ensure soft migration in future ? Here we will use Docker & Gitlab to ensure that our PHP code runs on these versions: 5.5, 5.6 and 7.0. We’ll use our own Docker images with configured additional extensions not provided by PHP official images, also with installed GIT and newest composer out of the box.

With this posts I want to highlight few things when staring with GO for new people which sometimes doesn’t seem so straight forward after reading https://golang.org/doc/install. #1 Install GO’s version 1.6+ there is no point to use any previous versions as with 1.6 version GO added vendor support (experimental in 1.5). What does it mean ? That dependencies are tight to a project not a global GO’s dependency catalog. If you come from PHP world you can compare it to global command for composer - yes, prior 1.
